Jiang Han did not blindly pursue high-level spells. Instead, she chose a purely Necromancy School combination of two fifth-level spells and one fourth-level spell.
[Extract Life Essence], used to pull off a desperate reversal, was a fifth-level necromancy spell that allowed voluntary recipients—no more than ten energy levels of living creatures—to offer up their life essence and heal the caster.
She only needed to buy more servant troops with weak mental attributes and brainwash them with hypnosis every day to gain a powerful healing method that other witches could only possess after acquiring a Divine Hamster Ball.
The second was the fifth-level necromancy spell [Undead Contract]. It could be cast on a recipient within line of sight but no farther than two hundred meters away, stealing three to five positive statuses from their body. If they had fewer than three positive statuses, it would instead inflict the negative effect of [Undead Mark]—reducing willpower and interrupting their train of concentration.
This spell perfectly handled witches who recklessly stacked powerful buffs, and it was difficult to counter.
The last was the fourth-level necromancy spell [Curse Invocation]. It randomly stacked one negative status from the following three: [reduction of physical abilities and magic power], [damage to willpower and concentration], or [sporadic severance of spinal nerve connections]—causing the body to lose control for roughly 0.1 seconds.
Using Curse Invocation in tandem with a large number of Undead Contracts could easily interrupt a witch's spellcasting by breaking her willpower.
Against witches with strong resilience, attacking their willpower and cutting off their train of thought was the better approach. At the same time, reducing the enemy's physical abilities or severing their spinal nerve connections were both extremely potent negative effects.
The three spells Jiang Han had chosen perfectly fit the traits and characteristics of necromancy spells:
